The invention provides a straightening control method and device. The straightening control method comprises the steps of acquiring a first mapping relation among a contact angle, displacement and a curvature of plate strip steel; obtaining a second mapping relation among rolling reduction, the contact angle and the displacement; determining a third mapping relation between the rolling reduction and the curvature through the first mapping relation and the second mapping relation; and controlling the curvature of the plate strip steel through the third mapping relation and the rolling reduction, and completing straightening of the plate strip steel. By obtaining the mapping relation among the contact angle, the displacement, the curvature and the rolling reduction, the third mapping relation of controlling the curvature of the plate strip steel through the rolling reduction is determined, and control and treatment of straightening of the plate strip steel are facilitated.
Description
Technical field [0001] The invention relates to the technical field of industrial control, in particular to a straightening control method and device. Background technique [0002] The straightening machine, especially the roller straightening machine, makes the strip steel undergo a series of repeated processes of plastic deformation, elastic recovery, plastic deformation and elastic recovery through repeated bending effects on the strip steel to achieve elimination The purpose of the original shape defects of the strip steel and the reduction of residual stress is to ensure that the strip steel products with good strip quality are obtained. Therefore, the roller straightener used for the straightening of medium and heavy plates is mainly used to eliminate plate shape defects and reduce the residual stress in the plate and strip steel to obtain products that are as straight as possible; used at the entrance of pickling and post-processing production lines Straightening machine,...
